CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 496,338, dated April25, 1893. Application filed June 25, 1892. Serial No. 438,061. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM H. CLARK, a citizen of the United States,residing in the city of Erie, in the county of Erie and State ofPennsylvania, have invented certain new and useful Improvements inCash-Registers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, forming part of this specification.

My invention consists in theimprovements in cash registers hereinafterset forth and explained, and illustrated in the accompanying drawings inwhich- Figure 1, is a front elevation of my improved cash register,portions of the case being broken away so as to show parts of theinternal mechanism thereof. Fig. 2, is a transverse vertical section ofthe same on the line :1", 00, in Fig. 1, looking in the direction of thearrow. Fig. 3, is a top or plan view, showing the relative arrangementof the key arms, one of which is shown in full. Figs. 4, 5, and 6, aredetail views of different parts of my improved cash register.

Like letters refer to like parts in all of the figures.

This invention is designed as an improvement on the construction shownand described in my application for patent, filed in the United StatesPatent Office, April 9, 1892, Serial No. 428,493, and its objects arehereinafter fully set forth in the following specification and claims.

In the construction of my improved cash register shown in the drawings,A, A are the ends of the upright portion of the frame, B is the front ofthe case, and B is the base thereof.

Secured between the ends A, A of the frame, near the upper and lowerportions thereof, are longitudinal semicircular bars 0 and C. These bars0 and O are provided with grooves DD, to receive register bands E, andin which grooves these register bands are moved as 50 hereinafter setforth.

In the bars 0 and 0 between the grooves D and D, are holes in whichvertical rods F carrying indicator tablets F move freely up and down. Tothese rods F, are secured key arms G which project out through the frontB of the case, when they are provided with operating knobs or buttons G.The rear ends of the arms G have also thereon cam shaped projections H,as and for the purpose hereinafter set forth.

A short distance above the front edge a of the longitudinal bar 0, alongitudinal bar I is secured between the ends A A of the frame, andbetween the edge a of the bar C and the bar I, in line with each of thegrooves D in the bar 0 is secured a vertical strip or guide of metal I,over which the register bands E pass. These register bands E areprovided in one edge thereof with serrations or notches b, and on theirface or outside surface with figures (Z- opposite each of saidserrations or notches, as and for the purpose hereinafter set forth.

In the edges of each of the vertical guides I, near the upper endthereof there is a notch or recess 6 directly under the serrations inthe edges of the bands E.

On each of the arms G is pivoted a horizontally moving spring actuateddog f, the outer end of which rests against the edge of the verticalstop or guide I, and, as the arm G is raised, enters the notch e thereinand engages with one of the teeth formed by the serrations b in theregister bands E, and carries the band E around the grooves D D in whichit rests a distance equal to one of the serrations or notches in theregister band E, this operation only taking place during the lastportion of the upward traverse of the arms G.

Pivoted to the ends A, A, of the frame are 0 levers J and J connectedtogether by means of a link K pivoted between them. Extendinglongitudinally between the free ends of the levers J is a rod L whichrests upon all the arms G when they are in their normal 5 positions asshown in Figs. 1 and 2, and between the free ends of the levers J isalso a rod L which in its normal position rests on the rear edge a ofthe bar 0, and which when raised is adapted to pass up around the camsH., on the rear ends of the arms G, so that when any one of the arms Gis raised it carries up the rod L with it, which operates through thelevers J and J and the link K connecting them together, to also move therod L up so as to pass over the cam H of the remainder of the arms G,and under the inclined portion h of the lower portion of the cam H onthe arm G being raised, until it assumes the position illustrated inFig. 5, it so operating as a lock for all of the arms G excepting theone being then raised.

To the ends A, A of the frame are also pivoted spring actuated ratchetlevers M and M, the ratchet lever M pivoted to the end A of the frame,being adapted to engage with a projection on on the end of the rod L, sothat as the rod L is being moved upward it must make its full traversebefore it is disengaged from the teeth on the lever M, while the teethon the ratchet lever M pivoted to the end A of the frame are adapted toengage with a projection m on the other end of the rod L, so that as therod L is being moved downward it must make its full traverse downwardbefore it is disengaged from the teeth on the lever M so as to be againraised. Thus when one of the arms G is started on its upward traverse itcannot be returned to its normal position until its upward traverse isfully completed. Meanwhile every other arm Gis locked in its normalposition by the rod L, until the one being operated has completed itstraverse and been returned to its normal position.

There are also pivoted to the ends A A of the frame bell-crank levers Nand N, the arms at thereof projecting outwardly through the front B ofthe case where they are coupled together by means of a longitudinal rod0. The upwardly extending arms n of said bellcrank levers N and N extendupward a sufficient distance so'that when the rod L is raised to thefull extent of its upward traverse the upper ends of said arms 17. passunder it, and retain it in such raised position until the operatorpresses upon the rod 0 which operates to move the arms '11, back fromunder the rod L, so as to allow it to move downward to its normalposition.

On the axis of the bell-crank N is an arm M, which extends downward intothe base B, where it engages with inclined surface 10 on spring actuatedlever P pivoted to the side of the base, which lever P is provided witha hook p on the outer end thereof adapted to engage with a catch Q on acash drawer R operating in the base B of the machine, and retain it in aclosed position against the tension of springs S, S, which are adaptedto force the drawer open when the hook p is released from the catch Qthereon, which operation is performed by pressing downward on the rod 0by which means the arm n of the bell-crank lever N is moved upward onthe incline p of the lever P so as to force it downward, and disengagethe hook thereon from the catch Q on the drawer R. For retaining thebell-crank levers Nand N in their normal positions springs T extendtherefrom to stud pins in the base B of the frame, at each side thereof.

To the end A of the frame an alarm bellV is secured, and to the arm n ofthe bell-crank lever N is secured a bell hammer lever to which bears abell-hammer w, which strikes an alarm on the bell V each time the rod 0across the front of the case is depressed.

Across the front of the machine a little in front of, and below thelower edge of the semicircular section 0 around which the register bandsE pass, I secure a bar If, in which I mount dials t the axes of thehands r passing through said dials when they have secured thereto starwheels 0 adapted to engage pins 0 in the register bands E so that eachtime a register band E travels completely around, the pin 0' therein,engages with one of the teeth of the star wheel 0 and moves it forwardcarrying the hand 0" forward one space on the dial 0", so that at anytime an inspection of the dials 1' will show the number of times eachregister band has traveled completely around from the starting point,zero.

In operating this machine the operator raises the arm G indicating theamountto be registered which operates to raise the indicator rod and thenumber thereon, and at the same time move the corresponding registerband E forward one notch, so as to register the like amount. When it isdesired to return the arm G to its normal position the operator pressesthe rod 0 which operates to release the arm G and it then returns bygravity to its normal position.

Having thus fully described my invention, so as to enable others toconstruct and operate the same, whatIclaim as new, and desire to secureby Letters Patent of the United States, is-
